To all whom it may concern:

Be it lmown that I, EDMOND VAcNEox, a citizen of the French Republic, resident of Clermont-F errand, in the Republic of France, have invented certain new and useful Improvements in Devices for Strengthening Rail-Joints, of which the following is a specification.

This invention consists essentially in a support for railway joints comprising two cross ties connected together by two longitudinals, the whole forming one block of reinforced concrete and intended to be placed only under the points of rails that bear throughout their length upon ordinary cross ties.

.The object of this invention is to strengthen the track by improving the joint which is well known is the weak spot.

This support in one piece differs fundamentally from the assemblages of cross ties and longitudinals already known hitherto, even though the metal parts that are thus assembled are embedded in cement.

This support is of reinforced concrete, that is to say, it consists of concrete and of an assemblage of steel bars that constitute a reinforcement in either direction. The assemblage is so arranged according to the known state of the art, that the compression strains will be absorbed mainly by the concrete, while the tensile strains will be absorbed mainly by the steel bars and the shearing strains will be taken up by both materials together.

In this manner an assemblage is provided which is practically indeformable and has a very long life and comprises no mechanical joints or connections, and is cheap to make.

In the accompanying drawings, which illustrate a constructional support according to the invention, 7

Fig. 3 is a vertical section on the line b-b parallel to the axis of the track.

constitute the support composed of one piece. The rails 3 rest on the longitudin'als by means of flanged metal chairs 4 and the packing pieces 5 composed of relatively yielding material. The centers of gravity of these chairs are situated between the axes of the cross ties of the support. The rails are attached to the support by screw spikes 6 screwed into spirals of the Thiollier type 7. forming one piece with the mass of reinforced concrete. The rails, connected by a non-supported or overhanging joint, that is to say, not bearing upon the support, are connected together on one side of the track by angle fish plates 8 and on the other side by simple fish plates 9. All these fish plates are held in place by bolts 10. The angle fish plates which are bolted to the rails as Well as to the support, are designed to prevent longitiudinal displacement of the rails, and they are located alternately on the right and left of the successive supports.

The location of the chairs 4 between the axes of the cross ties has the result that when the wheel of a train approaches the end of a rail, the pressure exerted upon one of these chairs will be transmitted to the ballast by the entirety of the support. This arrangement avoids the rocking of the support which Would take place if the pressure were to act, first on one edge of the support and then on the other edge, as would be the case if the rail supporting surfaces Were located on thecross ties 1, as has hitherto been the practice.

What I claim is 1. A support in one piece comprising two cross ties connected together by longitudinals, said support being located solely under the rail joints and consisting of a block of reinforced concrete, said support being provided with bearing surfaces for supporting the rails, the ends of which latter are unsupported or overhanging, the centers of the bearing surfaces being located between the axes of the cross ties.
